SHEAF-ELEVATOR.

Specification of Letters Patent.

Patented Nov. 1, 1921.

Application filed November 17, 1919. SeIialf'No. 338,560.

1 '0 all'ivhom it may concern Be it knownthat l, ABRAHAM MIDELLI N GER, a citizen-of the UnitedStates,"residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Sheat- Elevators, of which the following is a specification'.

This invention relates to elevators-forraising, directing and depositing hay, grain,

straw or other loose'materials in sheaves-0rotherwise, such elevators comprising an endless carrier havinga vertical part and an upwardly and outwardly inclined part in continuation thereof. a

It is 'often necessary in the operation of these-"machines to swing the inclined dis charging end laterally, so that it might be" presented in a different direction and-dis eharge'at a diiferent point: To properly brace and support the carrier and its=fraine,* the machinehas hithertoi been attached piv otally at two differentpoints, the lower piv otal' or swiveling attachment being a universal joint at the base of the frame and connecting the driving gearing, whereas the upper PlVOt 1s at or near the point of unc tionof' a transverse bar or stay with the" charge, which is a cumbrous proceeding,lia-

ble to cause injury. Furthermore, the two pivotal points aS hitherto constructedare considerably out of line vertically, involving great strain on the carrier, the frame and other parts whenever this swivelingoperation occurs. I

Toavoid these "objections I locatethe upper pivotal point on-the frame of the elevator, andma'kethe vertical part of said frame in two sections, the upper section'being centrally pivoted at its lower end on the upper end of'thelowersection. As the two pivots are nearly in'the' same vertical line and the lower pivot is madeslightly loose" on its bearing to avoid all strain, the upper section of the frame turns freely and is properly supported "at thesetwo points in doing so,

leavingthe lower part of the frame, with all its gearing and attachments, quite "undis tar-bed; 1

My invention consists in the above described improved construction and in some additional details of construction and combination hereinafter particularly set forth.

In the accompaying drawings:

Figure 1 represents a side elevation of a sheaf elevator embodying my invention attached to the frame of a barnpartly sectioned, the nearer side board of the guide trough for the inclined upper extension of the carrier having been removed.

Fig. 2 represents a cross section on the line mm of Fig. 1 looking downward, the barn wall not being sectioned, and the gearing being shown in plan view.

F i 3 represents a front elevation of the sheaf elevator at right angles to Fig. '1 looking from the right.

Fig.4 represents an enlarged detail view in side elevation of the upper pivot and its means ofattachment to the frame, the bar whi'chitenters being partly broken away.

Fig. 4 represents a plan view of the same.

Fig. '5 represents an enlarged detail view in side elevation of the lower pivot and the bearing in which it turns, the latter being shown of such size as to allow some play of said pivot and avoid binding and strain.

Fig. 5 'represents a vertical sectional view of the same.-

A' designates a wall of a barn to which, near the bottom, a casing B is attached atfording bearings for the driving gearing. As shown, this mechanism consists of a driving belt wheel C, a bevel wheel D turning therewith, an intermeshing bevel wheel E and a sprocket wheel F connected to a sprock wheel I at the lower end of the endless conveyer or carrier J by a short endless chain G held taut by an adjustable clamp H attached to the lower section of the frame. e donot confine ourselves to this precise arrangement and combination of gearing, as the same may manifestly be considerably changed by substitutioii of well known equivalents. There is no universal joint or other pivotal device between the belt wheel C and'the other gearing or anywhere else in the driving mechanism. The carrierJ travels over sprocket wheels j y" 3' j in a manner-heretofore known as well as over its lower sprocket wheel J, which last is on the sameshort transverse shaft K as the sprocket wheell aforesaid. This endless carrier in said conveyer. It comprises an inclined part or section 3 and a vertical part to which said inclined part is jointed. This vertical part consists of a lower section 1 and an upper section 2. At its lower end the section 2 is provided with a sheathing or shield 3 of U shape extending under said frame, and a pivot pin 4 centrally arranged and extending downward into a bearing socket 5 in the center of the crown of the lower frame section 1. The latter is of the shape of an elongated U inverted and narrowed at its upper end to form said crown.

Its lower ends are supported bybracket B and provide bearings for the shaft E of bevel wheel E and sprocket wheel F. The above construction, combination and arrangement of frame sections 1 and 2 and piviot pin 4 in central alinement with them permit section 2 to turn on section 1 without getting out of alinement therewith.

The upper pivot 6 is attached to the side of section 2 by a plate 7 bolted thereon, see Figs. 1 and 4. Said pivot pin 6 is presented downward, entering a bearing socket 8 in the end of a bar M projecting horizontally from the barn wall toward the elevator. The two pivots 4 and 6 are nearly in alinement and the slight discrepancy in this respect is allowed for by making the lower socket 5 somewhat larger than the pin 4, as shown in Fig. 5. Consequently there will be no injurious binding at these points.

The inclined uppermost part 3 of the frame and the corresponding part of the carrier maybe directed at will to dischargeover any desired point in a wide sweep without moving or disturbing the lowest section 1 of the frame or the gearing at its base at all.

The section 2 is preferably of T hape in cross section, presenting its broad face away from the barn and parallel to the wall thereof. Said section is provided with pairs of convenient brace bars LN extending to the wall of the barn and to a bar P which extends horizontally from the upper part of said section 2, affording a bearing for the shaft R of sprocket 3' which is located in the bend of the carrier. From the ends of this shaft brace bars 0 extend up to inclined part 3 ofthe frame.

Said part 3 is provided with a broad guide trough to prevent lateral scattering of the material brought up by the carrier. Short converging bars 25 and a, Fig. 1, afford a pivot for a lever 9 which bears the lower sprocket wheel j of the pair of terminal sprocket wheels. The end of this little lever i jointed to an adjusting rod V which passes through a lug W attached to part 3 of the frame and is screw threaded to engage a nut X beyond said lug. By turning this nut to draw on said rod and said lever the sprocket wheel 7' is caused to bear against the inside of the downward. flight of the carrier J and make its discharging end more truly vertical and also acts as a chain tightener.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:.- t

1. An elevator provided with a sectional frame, said frame having an upper vertical section which is pivoted at two points in different horizontal planes, and a lower section arranged to remain motionless relatively to said vertical section.

2. An elevator provided with a sectional frame, said frame having an upper vertical section, an endless carrier mounted on said frame, said frame having its upper vertical section pivoted at two points substantially in line vertically.

3. An elevator for sheaves of grain, having a frame consisting of an inclined upper section and a vertical part comprising a lower and an upper section, the latter section being pivoted at two points practically in vertical alinement.

4. In an elevator the combination of'an endless carrier with a frame for the same consisting of three connected sections, and a pivot supported by a fixed structure and connected to the upper portion of the middle section of the frame, for allowing horizontal turning of said middle section, the latter being connected to the lower section of the frame but free to turn horizontally thereon.

5. An elevator having an upright frame in three sections arranged end to end, the lowest section being stationary, the uppermost section being inclinedand pivoted to the middle section and the middle section being connected to the lowest section by a 1 section for allowing horizontal turning of said middle section, the latter being connected to the lower-part of the frame by a vertically disposed loose pivot substantially alined with the first mentioned pivotal conname to this specification in the presence nection to permit free horizontal turning of two subscribing Witnesses. movement of the middle section relative to said lower section and slight compensating ABRAHAM DELLINGER' sliding movement to allow for the slight Witnesses: relative displacement of the pivots.
